SANY 20 ton conventional truck mounted crane

SANY 20 ton conventional truck mounted crane 

Main features

Excellent and stable chassis performance /chassis system
Double-axle drive is used, providing good trafficability and comfortableness under complex road condition with reliable traveling performance.
Engine has the multimode power output function, which reduces power consumption.

Ultra long and super strong boom system
Four-section boom of high strength steel structure and optimized sexangle cross section reduces weight significantly with higher
safety rates. Jib mounting angles are 0°, 15° and 30°, which ensures fast and convenient change-over between different operating conditions so as to improving working efficiency of the machine.

Highly efficient, stable, energy-saving and adjustable hydraulic system
Triple gear pump, load feedback and constant power control are applied to provide strong lifting capacity and good micromobility.
Unique steering buffer design is applied to ensure stable braking operation.

Safe, stable, advanced, and intelligent electric control system
Self-developed controller SYMC specially for engineering machinery is configured. The adoption of CAN-bus full-digital network control technology ensures stable control signal, simple harness and high reliability. Timely feedback of data information can achieve the monitoring of the overall working status in realtime.
The load moment limiter equipped with the comprehensive intelligent protection system is used with accuracy within 3% to provide a comprehensive logic and interlock control, thus ensuring more safe and reliable operation.
